e'it known that I, RALEIGH J'. HrMMnL- RIGHT, 'a citizen of the United States, resid-s ing at New York city, in the county of New York and State of N ew York,

certain new and useful Improvements in Locomotive Furnace Constructions, of which the following isa speciiicationi t yThis invention' has reference. tothefpro- .vision of means designed especially 'for use in locomotive furnacel devicesy whereby an additional supply of airto mix with the com# bustion gases is carried into the fire vboXl through openings in the side waterlegs of the hre box and is distributed equally fromy openings which are preferably spaced near sheets 8 and 9 with a flue sheet the top of across bridge wall located a short distance tothe rear of the fluesheet. One of the objects of this arrangement is to get a suiiicient supply of airdirected inthe most advantageous manner and thus to se-` `cure more satisfactory combustion.

A further object of Ytheinvention is to supply means whereby air may be admitted to the iire box through pipe conduits inserted inferrules side water legs'to the atmosphere, the pipe conduits extending through 1a cross wall in the fire boX. s s

The above'as well as such other objects as, may hereinafter appear, I attain hymean's of a construction which I have illustrated in preferred form in vthe accompanying drawings wherein: Figure lis a longitudinal*vertical sectional view through a locomotive fire box showing my improvements applied thereto;

Figure 2 is a transverse sectional view taken on the line 2-2 of Figure 1 and Figure 3 is a partial plan view, the side walls being shown in section on the line 3-3 of Figure 2.l

Referring now more particularly lto Fig ures' 1 and 2, it will be seen that Iliave therein shown a locomotive fire box comprising outside sheets 4, 5, 6 and 7 and inside side 10, throat sheet 10a, and crown sheet 11, all'arranged substantially as isy customary in this class of apparatus.

Extending backward and upwardy from the front vwater wall 12 there are a series ofy arch tubes 13 curved as shown and connecting with the rear water wall above the fire door, these tubes being arranged to support the brick of an arch 14,.
